Abstract
One of the motivations for the researches leaded by the members of Vienna Circle with regard to the foundations of scientific language is found on Wittgenstein’s “Tractatus Logico-Philophicus”. Even though there are divergences about the legitimacy of this influence, thebook was, in effect, taken as a theoretical motivation for the structuring of scientific language, developed by logical empiricists. This paper will present the theories developed by members of Vienna Circle emphasizing the elements presents in Tractatusthat were taken, largely, as influence over the “criterion of meaning” of a philosophical proposition adopted by logical empiricists in an attempt to set a foundation for knowledge.
